Lapho ukhetha abahlinzeki benqwaba yamashidi, kubalulekile ukucabangela ikhwalithi nokuthembeka kwemikhiqizo abayinikezayo. Izinqwaba zamashidi ensimbi ezakhiwe ezibandayo kufanele zihambisane nezindinganiso zemboni kanye nokucaciswa kwazo ukuze kuqinisekiswe ukusebenza kahle kwazo ezinhlelweni zokongiwa kwamanzi namaphrojekthi wokudonsa amanzi. Ukwengeza, abahlinzeki kufanele banikeze amanani ancintisanayo okunqwabelanisa amaphepha angena ngaphakathi kwesabelomali sephrojekthi ngaphandle kokuyekethisa ikhwalithi.
Izinqwaba zeshidi eligoqiwe elibandayosekuyisinqumo esidumile samaphrojekthi wokongiwa kwamanzi kanye nokukhipha amanzi ngenxa yamandla awo aphakeme nokuqina kwawo. Ikwazi ukumelana nokugqwala okuhle kakhulu futhi ingamelana nezimo zemvelo ezinzima, okuyenza ibe yisixazululo esihlala isikhathi eside sengqalasizinda yokulawulwa kwamanzi.

Kunezinhlobo eziningi zezinqwaba zamashidi ensimbi, ngayinye inezici zayo ezihlukile kanye nezinzuzo. Ukuqonda izinhlobo ezahlukene zezinqwaba zeshidi lensimbi kungasiza ekukhetheni inketho efanelekile kakhulu ngezidingo ezithile zephrojekthi.

Kafushane, ukusebenza kwezinqwaba zamashidi ensimbi ezakhiwe ezibandayo kumaphrojekthi wokongiwa kwamanzi kanye nokukhipha amanzi kubalulekile ekudaleni ingqalasizinda esimeme futhi eqinile. Ngokubambisana nomuntu onokwethenjelwaumphakeli wenqwaba yeshidienikeza amanani okuncintisana enqwaba yamaphepha kanye nokukhethwa okubanzi kwezinhlobo zenqwaba yamakhasi, abaphathi bephrojekthi bangaqinisekisa ukuqaliswa ngempumelelo kwesixazululo esihlala isikhathi eside sokulawulwa kwamanzi.
